LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented May a, 1915.

Application filed March 24, 1913. Serial N 0. 756,608.

To all whom it may concern Be it known that I, JOHN G. Hnnens, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Loose-Leaf Binder, of which the following is a specification.

The object of my invention is to provide a binder for loose leaves or forloose leaf books of simple, durable and inexpensive construction.

A further object is to provide a binder employing a sleeve and screw correspond ingly screw threaded and provided with simple means for locking them in any of their relative positions.

My invention consists in certain details, in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows an end elevation of a loose leaf book binder embodying my invention, the dotted lines showing the device in its fully extended position. Fig. 2 shows a 1011- gitudinal, vertical, sectional View through a book lying flat, and I am giving the refmy improved book binding device. Fig. 3 shows an inverted plan view of a portion of one side of my device. Figs. 4 and 5 show detail, sectional views of portions of the mechanism. Fig. 6 shows a detail view of the outer end of one of the screw heads, part of said head being broken away. Fig. 7

modified form. Fig. 9

plan view of said 7 shows a longitudinal, vertical sectional view through a portion of the modified form of my improved binder. Fig. 10 shows a sectional, detail view illustrating the ratchet and spring pawl of the modified form, and Fig. 11 shows a detailed view of a part of the preferred form of the binder.

In the form of my device shown in Figs. 1 to 6 inclusive, I provide two body members, each comprising a horizontal wall 10 and a vertical wall 11. In this description, am assuming that the binder is used with erence numerals applied on the parts on the accompanying drawings. The members 11 rest adjacent to each other, as shown in Fig.

1 and are designed to slide vertically with relation to each other.

Substantially in the middle of my binder from end to end thereof, I provide connectlng means preferably constructed as follows: Secured to the member 10 of one of the body members of my binder is a sleeve or cylinder 12 extending toward the other member '10 parallel with the members 11. Secured to the member 10 of the other body member is a pin or cylinder 13 slidably received within the sleeve 12 and having at its free end an enlarged head 14. The free end of the sleeve 12 is contracted at 15 to limit the telescopic movement of the sleeve 12 and the member 13 with relation to each other. Between the head 14 and the adja cent member 10 is an expansible coil spring 16 designed to yieldingly hold the sleeve 12 and the pin 13 at the outward or extended limit of these movements-with relation to each other. 7

Secured to one of the members 10 is a part of an adjustable fastening device whiohI shall now describe: I preferably employ two adjustable fastening devices, one of them being near each end of the binder. These devices are of similar construction and I shall therefore describe but one of them. I provide a flat bar twisted to form a screw threaded portion 17 and having at one end a portion 18 bent at right angles to the portion 17. The portion 18 is not twist-' ed. The portion 18 may be secured to the opening to receive the sleeve 21 and provided with a central raised portion to receive the flange 22, and having a portion 24: folded or bent over the free edge of the portion 10. The plate 23 is secured to the portion 10'by said rivet 19. Slidably and rotatably mounted in the other wall or portion 10, I provide a cylinder 25 which telescopically receives the portion 17 and is provided in its wall with screw'threads 26 which coact wlth the screw threads formed by twisting the portion 17. The cylinder 25 is received within the sleeve 21.

On the outer end of-the cylinder 25 outside the body portions of the binder is a head 28 having a slot 29 to receive a screw driver. Theunder or inner side of the head 28 is provided with a plurality designed to engage and coact with lugs or I portions 31 which may be made by punching the cylinder 25 may small holes in the portion 10 around the cylinder 25 and pressing the-parts 31 out wardly. The edges of the leavesof a book 32 are placed between the portions 10 of my binder and are provided with holes to re- 2 ceive the sleeves 12 and 21 and the, cylinders 25 and 13.

In the. practical use of my improved binder, I preferably use I the binder with leaves having slots to receive the members be replacedafter the leaves have been placed overthe cylinders 21. As long as the. spring 16 operates the binder will be held locked by means of the lugs 31 and the notches 30.

In Figs. 7 tolO inclusive, I have shown a modified form of my deviceespecially designed as a loose leaf binder where no back members are used. Inthe form of. the device, shown in Figs. 7 to 10, I have provided one bodymember comprised of a channel which maybe, if desired,;substantially rectangnlar in cross section'with part ofiits outer wall cutaway. I have indicated the member just described by the reference numeral-35.; Extended through the member 25 is atwisted bar 17 having a right angled extension 18 secured to the member 35 by the rivet19. I preferably provide members 17 near each e ndof the member 35. The mem ber 35 is designed to rest against the leaf mounted on, or a bookmounted on. the mem bers 17.

I provide another body'imember of the modified form ofj my device comprising a horizontal wall 37, the edges of which are turned-upwardly to form vertical walls 38.

The upper edges of the walls 38 are turned toward eachotherto form short horizontal walls 39. In the walls 39 I cut a plurality, of slots 40 ,andj press a small part of the;

of notches 30,

2 device.

material downwardly forming engaging devices 41. t The wall or plate 42 has its-edges received between the walls 39 and the engaging devices 41 on each side of the body member now being described. Other forms of body members may be used, the essential features being to provide a body member substantially rectangular in cross section which may be easily assembled.

j Rotatablymounted in the plate 42 in line with the members 17 are cylinders 43 which extend outwardly away from the binding On the inner endsof the cylinders 43 between the plate 42 and the wall 37 are ratchet wheels 44 mounted on the cylinders, 43. The walls of the cylinders 43 are pro vided with screw threads or screw threaded indentations 45.. The cylinders '43 are de-.

signed to receive the twisted bars 17 and the screw threads 45 are designed to, coactwith said twisted bars.

It will readily be seen that by locking the ratchet wheel 44,- the members 17 and 43' may be locked with relation to each other. For locking the ratchet wheels 44 in any position of their movement, I provide springs between the wall j37,andthe plate 42which may be described as follows:,I provide'av spring having a member 46. designed to engage one of the walls 38, a

transverse member 47 and an inclined mem-.

ber 48 designed to engage the .other'wall 38. The form of said spring may be varied as desired, it being my purpose to .pro-

vide a spring which will be held frictionally between the walls 38.

Formed on the member 46'is an extension 49 designed in one position. of the sliding movement of said spring to engage the teeth extends through a slot 50 in the plate 42 to position where it is'readily accessible from outside. the binder.

In the practical use, of the modified form: of my "binder, the members 17 are extended f of theratchet wheel 44. The extension 494 through holes 50 in the leaves of a book; if

The cylinders 43 are droppedover the members 17 and the wall37 may be pressedtoa ward the member .35. and when the leaves of thebook are pressed tightly together the.

binder may be'lockedby pushing the eXten sion 49 into engagement with the ratchet 1 wheel 44.

My improved'boolr binder hasga great many advantages, many of which are obvious from the foregoing description. The 7 device is of comparatively slmple'and ine'xpensive construction. For [the .f screw threaded members 17 Iprovide' twisted bars and for the members 43 and 25, I provide screwthreadsmay be readily pressed.

It will be readily seen that a .great many variations may be made in the details of the construction of my device and it is 'my inordinary thin walledv cylinders into which Q tention to cover any variation of construction which may be included within the scope of the appended claims.

I claim as my invention:

1. In a device of the class described, a binder member designed to engage one side of a book, externally screw threaded devices carried by said binder member and designed to be received in holes in the leaves of a book comprising a twisted bar extending through said binder member and provided with a right angled extension secured to the surface thereof, a second binder member designed to engage the other side of the book, a plurality of hollow cylinders mounted thereon, each of said cylinders having'screw threads formed in its walls and being designed to receive one of said first named screw threaded members, and means for locking said cylinders and screw threaded members in various positions of their movement with relation to each other.

2. In a device of the class described, spaced binder members,

a screw threaded engageing device mounted on one binder member, a coacting screw threaded engaging device rotatably and slidably mounted in the other binder member yielding means for holding said binder members apart, a head on the second engaging device outside the binder member in which it is mounted, said last named member and said head being formed with portions adapted to coact and prevent rotation of the second engaging device when the binder members are at the limit of their movement, away from each other and to become inoperative and to permit rotation of the second engaging device when the last described binder member is moved toward the other binder member slidably on the second engaging member.
